 *       Cure/Dry CharacteristicsGUHUA/GANTEXING: The following chart shows the typical drying time/cure rate of white topcoat formulations based on THYON OX787. Evaluations of Gardner Circular Dry Times are very interesting. The dry times will normally lie somewhere within the area plotted on the chart below. Pot life was determined with a recording Brookfield viscometer and is defined as the time required to double the initial viscosity of approximately 250 centipoise. The pot life will normally be between 4 and 8 hours when measured by this method.

Formulation TipsPEIFANGJIQIAO

» CrosslinkerJIAOLIANJI: For maximum gloss retention properties, aliphatic isocyanates are recommended. Also the Trimer or Biuret versions of hexamethylene diisocyanate can be used.

A ratio of 1.05: 1 of isocyanate to hydroxyl is normally recommended in the industry.

» Solvent: RONGJI Ketone solvents will give the best viscosity –VOC due to a combination of good solvency and low density. Aromatics such as xylene and toluene provide good solvency and can be readily used in combination with the more polar solvents. Glycol ether acetates can be used but normally do not provide low viscosity/VOC. PM-Acetate should be avoided due to its film retention characteristics. Avoid alcohols and glycol ethers; their hydroxyl functionality can react with the isocyanates.

» CatalysisCUIHUAJI : Catalysis with 0.005% dibutyltin dilaurate on total binder solids is normally recommended. Higher catalyst levels will result in shorter pot lives and faster cure rates.
